Onetime parsing of HTTP request The Internals of Functions ? The main role of is to listen for HTTP requests through and return responses to the client。 however, it has other duties, such as: ? Managing TCP connections. ? Validating HTTP requests ? Routing HTTP requests to the correct application pool. ? Caching of responses in kernel mode. ? Performing all textbased and centralized binary logging for the Web service (not ODBC). ? Implementing features such as connection limits, connection timeouts, queuelength limits, and bandwidth throttling for IIS. Https Cache Flow IIS New Isolation Mode ? 應(yīng)用程序隔離的目的 ? IIS ? IIS ?
